    Hello everyone - have been enjoying your posts and links!

    Here's some photos which you may find somewhat puzzling and worth considering.

    When the inductance in emitter-base coil is reduced the AV Plug+LED array connected to the ground (on the right in photos) is all lit but the AV Plug+LED array between it and the Exciter is not.

    What do you make of this?
    It looks to me there simply is not enough energy being cohered/converted from the environment to light all leds. So, one of the coils will suck up all the energy and nothing is left for the other. Since the coils are never 100% equal, once one of them comes into resonance, there will hardly be any energy left for the other one to pick up, even if they are 99.999% equal.

    It might be interesting to see what happens if you raise the frequency of the oscillator to make more energy available, which should happen if Naudin's paper is correct. If I understand the circuit correctly, you can try to lower the base capacitor from 400 pF to about 100 pF (take a trimmer, so you can adjust). That should double the frequency. And then see if you can find a resonant point.

      OK, not many takers in a day.

      Here is my understanding, if I'm ignorant, then I'm sure I will be corrected and gain from that.

      I can not describe precisely what is going on, but as I see it, the LEDs have to get a sufficient voltage to be lit.

      In both examples the weak group of LEDs is just barely lit, so voltage is present, but not enough to give strong light on the weak group..

      I think by varying the frequency you move the location of the standing wave voltage node(s) relative to the anti nodes (zero or close to "zero") represented by ground and the collector of the MPSA06.

      The group "seeing" the major part of a voltage node is the one most bright.

        The fact that one group is barely lit, is actually quite smart illustrated by using 10 and 11 LEDs in the two strings in a group,

        It is then a kind of "VU meter" like the ones used on the old days on the tape recorders (yes I'm that old), a simple but accurate measuring instrument, bright idea

        • I got my setup working properly.

          Ive been playing around with lighting the led panels wirelessly, with them in close proximity to the receiving tower. The Towers are connected on one wire.The lights are slightly brighter when they are grounded, or in this case connected to a large metallic surface. Their intensity can be increased by placing them almost ontop of the "cups". I have a little copper tab that protrudes from the base of the cups, its where the top of the coil connects. It seems to be one of the hot spots, especially when lighting up that fluro.

          Lots of other interesting effects...

            @ Lamare & @ Eric

            Thank you for your responses. Eric the VU meter is a good analogy. A visual display which helps to see where the energy is flowing.

            I have a point to make but it is not "fully formed" and that was reflected in the vaugeness of my question.

            • SEC 15-3 survives 5 day harsh sea trials

              @ All
              I'm back from my 5 day sailing trip. I used the little SEC 15-3 for lighting each night for and hour or so. It ran the 5 days on a couple of series joined 9 volt batteries. My conclusion is that this amazing device of Dr. Stiffler's has a practical use on a boat. I ran a bunch of tests using it with and without the sea as the ground. The most practical use was at the dinnete table as a pleasent light for dinner. The trip was a rolling experience with all the anchorages being open and exposed to the sea swells. The little SEC hung in there and survived. Here is a brief video of one of my experiments and what the island I sailed to looks like.

                Really nice way to do your tests!

                I watched the video, and just couldn't suppress a big grinn on my face. Cool!

                • Tons of fantastic replications,

                  I would be interested to see people take the next step and start their calculations. May not be the most fun job, but im sure the good Doc will agree, its exciting to see hard work in solid form in front of your face, its a grin that's hard to wipe off.

                      Ren, i wanted to post some thing but i am blind now after looking at that thanks a lot mate Thanks for posting the trouble shooting stuff, ill be making up a lot of data of this with ours, just waiting for the new boards ATM and still tuning the older ones, have the spheres and electrolyzers built.

                        I agree.

                        Im looking forward to the challenge of measuring it accurately. From resting voltage measurements on my battery I can tell its very low power, but just how low? And how do I know if I am getting more light for less input?

                        @ Ash, thanks mate. Look forward to seeing some of your replications

                        @ All.

                        I found a strange effect today. I was helping a mate out that runs a warehouse. I brought the SEC over to show him, and was planning to just leave it running for the day, and measure the discharge of the battery at the end.

                        The roof is steel, and about 30ft high. The walls and floor are a mix of concrete and reinforced steel. So in someways it was like standing inside a big Faraday cage I guess, sort of...

                        Anyway, the FM radio was on and above us, about 20 feet away. Its aerial was homemade copper pipe with an aluminum grill, positioned precaroiusly but functioning none the less.

                        Any operation of the SEC made the radio detune to static. It was also possible to place your hand close enough to the tophat and it would make the radio go silent. No static even. Correct positioning of your hands over the towers could get the lights to go on dimly and the radio to work.

                        Weird.

                        I'll post a video of it running tonight.

                              • [QUOTE=ren;65715]Lol @ Jim.

                                Cant afford to nuke my computer so I will be looking for a barn too for future experiments, a faraday barn . Were you doing tests right next to it, or was it across the room?

                                Hi Ren,
                                The computer was about 12 feet from the exciter / transmitter itself but my wire to the other tower was running within 5 feet and diagonally above it. NOT GOOD! DO NOT DO THIS! ............. I should have known better as I beat one before when doing some of the cap charging experiments. But I'm back now and I'm making changes to where I fire this monster up. So After a major hardware setback I have recovered.

                                Details of the incident:
                                • I was running my exciter build of Doc's latest design as posted in the build document.
                                • I was moving a tap point down the tower winding by sanding away the lacquer from the magnet wire and soldering a tail to the bare copper turn by turn on both the transmitter and receiver.
                                • Doing this is the same as changing the number of turns in the inductor.
                                • This was in response to tests I ran with a grid dip meter looking at the resonant frequency of the L and top load C between the components built as specified and the ones I built with the donuts. Obviously they are not the same.
                                • BLUE SCREEN OF DESTRUCTION resulted from an undetermined cause.
                                • Exciter was still fairly poorly tuned as evidenced by the current draw of the transmitter and as stated by Dr. Stiffler some posts ago.
